WORCESTER, Mass. (AP) — A 7-year-old boy who came to Massachusetts to spend the summer with his father and who, prosecutors say, was severely beaten by him on Father's Day was declared "clinically dead."

Nathaniel Turner remained on life support at University of Massachusetts Memorial Medical Center in Worcester, officials said. A hearing is scheduled for Wednesday at which a juvenile court judge will decide whether to remove him from life support.

Relatives said Nathaniel had lived with his grandmother in Alabama before coming to live with his 36-year-old father, Leslie Schuler. Schuler recently had received a court order to have summer custody of the child.

According to police, the boy had been physically and mentally abused by his father for around eight weeks. On Father's Day, Turner suffered severe injuries when Schuler slammed the boy's head into a bedroom wall with such force that it left a dent in the wall, police said.

Schuler was charged with seven counts of assault and battery and three assault counts. He was held on $250,000 cash bail. His lawyer, Christopher Tully, said his client was remorseful.

Schuler's girlfriend, Tiffany Hyman, 28, was charged with two counts of assault and battery. Police said it appeared Hyman did not strike the child but she could have intervened and stopped the abuse. She was held on $50,000 cash bail.

Her lawyer, Jose Rosario, said police reports contained no information indicating his client touched the child.

Schuler and Hyman, both of Worcester, pleaded not guilty Tuesday in Central District Court. They will return to court July 21.
